Römerstein, Mountain summit in Baden-Württemberg, Germany.

The Römerstein is a mountain on the plateau of the Middle Kuppenalb in Baden-Württemberg, reaching 874.4 m above sea level as the highest point of that plateau. Its wooded crest rises only about 70 m above the surrounding land, on the Gemarkung Donnstetten in the municipality of Römerstein. At the summit stands the 28 m Römersteinturm, a timber-boarded tower on a solid stone base built in 1912.

In ancient times, Roman settlements developed near Donnstetten between 85 and 260 AD. The mountain itself was later named after the Rem family, who shaped the area during the Middle Ages.

The name does not come from the Romans, who settled in Donnstetten east of the mountain between AD 85 and 260, but from the Rem family, recorded in the area in the 14th century. The mountain gives its name to the municipality of Römerstein in the district of Reutlingen. The 28-metre tower was built in 1912 by the Schwäbischer Albverein after a donation drive, replacing a survey scaffold opened to visitors in 1899 and dismantled in 1904.

The observation tower opens during warmer months on weekends and holidays, with barbecue areas and playgrounds available for families. The hiking trails to the summit are well-marked, with the area remaining accessible throughout the year.

On very clear days the view from the 28 m tower reaches the Bernese Alps and, 260 km away, the Großvenediger in Austria. The tower was funded by donations and cost 9,500 marks when the Schwäbischer Albverein built it in 1912.
